最適条件を見い出すために、種々実験を行い、本発明を
完成するに至った。Aluminum has distinct properties such as melting point, viscosity (surface tension), solidification structure formation, etc. from iron and steel, and the conditions for stable casting of thin cast aluminum pieces are obviously different. Especially for moving molds that directly contact molten aluminum and form a solidified shell to form a pool of molten metal that forms a thin cast piece, conditions such as cooling characteristics and lubricity (ease of peeling) ) Should be fully considered. The present inventors have conducted various experiments to find the optimum conditions required for a moving mold, and have completed the present invention.

得られるもので十分である。As the ceramics in the present invention, for example, Z which has appropriate thermal conductivity and lubricity with respect to aluminum is used.
R 2 O 3 based ceramics or BN (boron nitride) based ceramics are preferable. However, when the moving mold is formed of a block of ceramics alone, strength is a problem, so it is desirable to have a ceramics laminated structure in which the back surface is reinforced with a metal such as steel. The ceramics used here may be obtained by a general method, for example, those obtained by kneading a fine powder raw material with a binder, molding, drying and firing.

十分な冷却速度を確保することができる。Cooling of the moving mold by the ceramics is performed by blowing air from the outside until the moving mold is separated from the slab and comes into contact with the molten aluminum, whereby the above-mentioned Al 6 Mn crystallized product is removed. It is possible to secure a sufficient cooling rate for crystallization to an appropriate degree.
